\footnotesize{$Notes$: *p$<$.1; **p$<$.05; ***p$<$.01. From second column all models of the form $R_{ic}= \beta_1 SMD_{ic} + \beta_2 MV_{ic} + \beta_3 SMD_{ic} \times MV_{ic} +\varepsilon$, but only the first term is reported. Models control for age, gender, seniority, regional or nationwide PR mandate, and United Russia affilation. Column 1 is the difference in means for $bw=1$ including controls. Dependent variable is the share of voting absence out of all votes across the whole convocation. Sample 1 includes only dual included deputies, Sample 2 additionally includes all majoritarian candidates. Std.errors clustered at the deputy-convocation level. Optimal bandwidths \citep{calonico2014robust} from top to bottom are: 0.14 and 0.20.} \end{minipage}} \end{table}
